A casting roll production process with electric furnace-refining-pouring was analyzed, and the principle of inclusion occurrence and its harm in each process were studied, cast steel roll inclusion control measures are put forward. By controlling the goal carbon content of original melt electric cooker, the deoxidizer was adopted to improve deoxidizing capacity, and the inclusion and melt process was simulated, to improve the capacity of refining slat absorb inclusion, the amount of inclusion was decreased and inclusion distribution was improved, the LF, VD refining process was carried out, so that the purity and performance of the roller can be improved. © 2016, Chinese Mechanical Engineering Society.
